Aqueous Solid-Liquid Interfaces at Atmoci Scale

Abstract

Atomic scale insight at the aqueous electrified solid-liquid interfaces is considered critical in further advancement of materials that could be implemented in electrochemical systems such as electrolyzers, batteries and fuel cells. The research effort aimed to fundamental understanding of processes that are relevant for energy conversion, storage and biomedical applications will be presented. It has been demonstrated that fine tuning of the material properties can lead towards unprecedented improvements in their functional properties [1]. This presentation will address unique research approach that is capable of revealing structure-function relationships in the design of nanomaterials for electrochemical systems. The following topics will be discussed: 1) well-defined materials obtained by varying their surface structure, composition profile and electronic properties [2]; 2) atomic/molecular insight into electrified solid-liquid interfaces; 3) identification of the active and the most vulnerable surface sites under reaction conditions; 4) insight into chemical nature between the surface atoms, reactants, and molecular species in the electrolyte; 5) engineering of advanced nanomaterials with desired size, shape and composition profile [3,4]; 6) ex-situ and in-situ characterization of tailored nanostructured electrochemical interfaces.
